Review Comment:
I suppose when "limited user" is configured, connections from those users
will be limited not rejected.
e.g.
```
kyuubi.server.limit.connections.user.limited.list=tom,jerry
kyuubi.server.limit.connections.per.user=10
```
user "tom" and "jerry" are limited to opening up to 10 connections for each
user, other users are not limited.
